How to Add a Signature to a PDF
The fastest way to add a signature to a PDF is the Sign PDF tool: upload your document, draw your signature with a mouse, trackpad, or touchscreen (or type it in a handwriting-style font), position it on the page, and download. This works on desktop and mobile, and the file never leaves your browser.

Three ways to sign, and when to use each
Drawn signature: closest to a real signature's look, best if you're signing with a trackpad, touchscreen, or stylus.
Typed signature in a script font: fastest option, reasonable for informal documents where visual authenticity matters less.
A scanned image of your actual signature: upload a photo of your signature on paper, then place that image on the PDF — this preserves your exact real signature's appearance.
Step-by-step
1. Open the Sign PDF tool and upload your document.
2. Choose draw, type, or upload-an-image for your signature.
3. Drag it into position on the correct page — resize if needed.
4. Download the signed PDF.
